Disclosed is a method for manufacturing detergent particles which includes a step (A) wherein an acid precursor of a non-soapy negative ion surfactant is partially neutralized with a water-soluble alkaline agent to obtain a partially neutralized acid precursor paste, and a step (B) wherein the partially neutralized acid precursor paste obtained in step (A) and a water-soluble solid alkali inorganic substance are mixed together; further disclosed are detergent particles obtained by means of said manufacturing method. This method for manufacturing detergent particles can be adopted as an optimal method because the obtained detergent particles have the advantages of being easy to measure during use and of dissolving easily in water due to the high free-flow characteristic and prevention of coarsening of the particles. |
